Check Digit Verification of cas no

The CAS Registry Mumber 894808-86-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,4,8,0 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 894808-86:
(8*8)+(7*9)+(6*4)+(5*8)+(4*0)+(3*8)+(2*8)+(1*6)=237
237 % 10 = 7
So 894808-86-7 is a valid CAS Registry Number.

Synthesis and photophysical properties of dihydroheptacenes: New blue-emitting materials

Mondal, Rajib,Shah, Bipin K.,Neckers, Douglas C.

, p. 4085 - 4091 (2007/10/03)

7,16-Dihydroheptacenes (1-3) substituted at the 6, 8, 15, and 17 positions are synthesized as blue emitters potentially useful in organic light emitting diodes (OLEDs). The photophysical properties of 1-3 (λmax = 424-428 nm, ΦF = 0.15-0.21, τF = 2.35-2.67 ns in CH2Cl2) are discussed. They are shown to be stable and efficient blue emitters in the solid state (ΦF = 0.37-0.44). The X-ray crystal structure of 1 is reported.
